you are right. I just do some calculation for my mount. My truesouth sat is G10Rat 123. Using this mount, the most EAST sat is AMC5 at 79W, at AMC5 position, the mount reaches its EAST limit, so we can make a save assumption that the "real" rotation angle of this mount is +/-45 degs (G10R at 123 - AMC5 at 79) = 45 degs.
If one needs wider rotation angle,
SG2100 mount might be a good mount to consider,which default limit setting is +/- 72 degs as I remember. You can manually adjust the EAST/WEST bars inside of the mount to make it turn further than +/-72 degs. I still like the built quality of
SM3D12, it drives my 1m dish without any problem. I wish it could turn EAST/WEST a bit further.

Just to check. I just went as far east and west on my motor ant the arrow on the mount gets close to 60 on each side. taking that calculation into the account 60/1.15=52.
This had me confused originally as well.
